Clinical Characteristics in Older, Middle-Aged and Young Adults Who Present With Suicide Attempts at Psychiatric Emergency Departments: A Multisite Study.

Abstract

OBJECTIVES\nTo study age group differences in clinical characteristics in older, middle-aged and younger adults with actual suicide attempts (SA).\n\n\nDESIGN\nCross-sectional cohort study.\n\n\nSETTING\n3 Swedish university hospitals.\n\n\nPARTICIPANTS\n821 persons who presented with self-harm at psychiatric emergency departments participated. Those with non-suicidal self-injury according to the Columbia Suicide Severity Rating Scale (C-SSRS) were excluded, leaving a total of 683 with an actual SA (18-44 years, n\xa0=\xa0423; 45-64 years, n\xa0=\xa0164; 65+, n\xa0=\xa096).\n\n\nMEASUREMENTS\nSuicidal behavior was characterized with the C-SSRS and the Suicide Intent Scale (SIS); symptoms associated with suicide were rated with the Suicide Assessment Scale (SUAS). Diagnoses were set using the Mini-International Neuropsychiatric Interview. Patients self-rated their symptoms with the Karolinska Affective and Borderline Symptoms Scale (KABOSS).\n\n\nRESULTS\nOlder adults scored higher than the younger group on SIS total score and on the subjective subscale, but no age group differences were detected for the objective subscale. Half of the 65+ group fulfilled criteria for major depression, compared to 3-quarters in both the middle-aged and young groups. Anxiety disorders, as well as alcohol and substance use disorders were also less prevalent in the 65+ group, while serious physical illness was more common. Older adults scored lower on all symptom scales; effect sizes were large.\n\n\nCONCLUSIONS\nWhile older adults with an SA showed higher suicide intent than young adults, they had lower scores on all ratings of psychiatric symptomatology. Low ratings might interfere with clinicians assessments of the needs of older adults with intentional self-harm.
